The Santa Fe Trail was a 19th century transportation route that connected Independence, Missouri with Santa Fe, New Mexico. William Becknell was the pioneer who opened the trail back in 1821 and it served as a vital commercial highway untill the introduction of the railroad in 1880.
The trail passed near the territory of the Comanches, who demanded a compensation for granting passage to the trail, this opened a new market for the american traders and also they had New Mexico isolated from it´s border with Mexico making it more dependent from the American market. By the year 1840 the traffic was so heavy along the Arkansas Valley that the bisons herds could not reach their seasonal grazing land contributing to their collapse, which was the fundamental rock of the decline of the Comanches.
The trail was important because carried manufactured goods from and to Indepence, Missouri and took advantage of the recent independent of Mexico from the spanish crown, it also helped the mountain men and the fur trapper by carrying food and supplies into the northwest. The Santa Fe trail followed several emigrants trails to the west that the pioneers pursued in front of the opportunity to hold a free land.
The route was vital for the invasion of New Mexico in the Mexican-American war in 1846 after which the state of Texas annexed new territories.
